The Timely Use of Prenatal Care and its Effects on Birth Outcomes in Black Women of Low Socioeconomic Status in the South
Despite substantial evidence linking improved pregnancy outcomes with receipt of prenatal care and recent improvements in prenatal care utilization, specific subpopulations continue to receive late prenatal care and experience adverse birth outcomes. This study will use the Health Belief Model and the Intersectionality Framework to examine the timing of prenatal care utilization, prenatal care compliance, and adverse birth outcomes within a group of low-income, black women in the South. Black women have worst rates of late prenatal care utilization and compliance than any other racial group. This late prenatal care utilization and compliance leads to adverse birth outcomes. A secondary data analysis was conducted using binary logistic regression and OLS regression to examine agency factors, structural factor, and risk health behavior in predicting timing of prenatal care utilization and compliance. In addition, this study also examines timing of prenatal care utilization and compliances and its effects on preterm birth and low birth weight. The results show that family size and knowledge/attitude significantly influences timing of prenatal care. Prenatal care compliance is influenced by church social support and low birth weight is influenced by private insurance. The results of this study show that although much is known in comparing different racial groups, more investigation is needed to explain why low income black women still experience less prenatal care use and compliance and worse adverse birth outcomes than any other racial group in the United States
From Stout to Plus: Identifying the Evolution of Apparel Sizing for Larger Consumers from 1913 to 1993
Ongoing discourse regarding womenâs apparel sizing standards, or lack thereof, reflects a collective sense of confusion both within industry and amongst consumers (DesMarteau, 2000; Kennedy, 2009; Schofield & LaBat, 2005). This confusion over sizing has been shown to lead to consumer frustrations with the fit of clothing, with plus size consumers experiencing a great amount of difficulty (Petrov & Ashdown, 2012). Issues of apparel sizing and fit and a plus size market are not a recent phenomenon. However, discourse regarding demographic trends that contribute to this growing segment has become increasingly pertinent in recent years
Perceptions of Teacher-Writers: Initial Influences to Write
This qualitative case study explores perceptions of teacher-writersâ early writing histories and examines their initial influences to write. Interviews and writing artifacts of ten K-12 teacher-writers serve as the primary data source. Findings indicate that teachers with strong identities as readers and/or writers in their K-12 experiences often received positive feedback which encouraged them to develop as writers, while teachers challenged with mechanics often received negative feedback which discouraged them from writing. Revisiting negative writing histories reshaped writing beliefs to influence a positive writing identities. The authors suggest practices for pre-service literacy courses to examine writing histories and to develop and nurture writing identities
The Dimensions of Teachers Who Write and The Essence of A Writing Life
The purpose of this grounded theory case study was to explore the perceptions among ten K-12 teachers who teach writing and also write themselves. What are the key essentials for teachers to sustain a writing life? What habits of mind or attitudes are necessary for teachers to sustain a writing life? Interviews served as the primary data source along with writing artifacts from the participantsâ own writing life. Findings indicate that teacher-writers committed to a writing life do so for the purpose of 1) discovering meaning, 2) connections to others 3) commitment to learning and 4) well-being, with an overall purpose of feeling alive both professionally and personally. Habits of mind or attitudes that were cultivated to sustain a purposeful writing life were: 1) a sense of awareness and curiosity 2) habits and rituals 3) solitude 4) overcoming fear and perfection. Findings suggest that teachers need personal reasons to commit to and sustain a writing life along with a cultivation of attitudes or habits of mind to sustain a writing practice
Evolving morphotropic phase boundary in lead-free (Bi1/2Na1/2)TiO3âBaTiO3 piezoceramics
The correlation between structure and electrical properties of lead-free (1-x)(Bi(1/2)Na(1/2))TiO(3)-xBaTiO(3) (BNT-100xBT) polycrystalline piezoceramics was investigated systematically by in situ synchrotron diffraction technique, combined with electrical property characterization. It was found that the morphotropic phase boundary (MPB) between a rhombohedral and a tetragonal phase evolved into a morphotropic phase region with electric field. In the unpoled material, the MPB was positioned at the transition from space group R3m to P4mm (BNT-11BT) with optimized permittivity throughout a broad single-phase R3m composition regime. Upon poling, a range of compositions from BNT-6BT to BNT-11BT became two-phase mixture, and maximum piezoelectric coefficient was observed in BNT-7BT. It was shown that optimized electrical properties are related primarily to the capacity for domain texturing and not to phase coexistence
Coordination changes in the early stages of learning to cascade juggle
The experiment was setup to examine the coordination changes in assembling the movement form of 3-ball cascade juggling. Eight adult participants learned to juggle over 4 weeks of practice. Juggling scores were recorded at each session and performance was videotaped at eight selected sessions for purposes of movement analysis. Once the basic spatial and temporal constraints on cascade juggling were satisfied, and the figure-8 juggling mode was established, temporal modulations of the relative motions of the hands were emphasized. All participants learned to juggle and the increase over practice in the number of consecutive balls caught was best fit with a power law. The non-proportional rate of performance increment was consistent with the qualitative changes in the form of the hand and ball movement kinematics that occurred over practice
Providing value to patients and providers via a pediatric statewide antibiogram in South Carolina
Abstract
Objective:
Antimicrobial stewardship has special challenges in particular populations and facilities, including pediatrics. We sought to augment the information available to antimicrobial stewardship programs (ASPs) by created a cumulative statewide antibiogram for neonatal and pediatric populations.
Methods:
In the Antimicrobial Stewardship Collaborative of South Carolina (ASC-SC), we created statewide antibiograms, including a separate antibiogram accounting for the pediatric and neonatal intensive care unit (NICU) populations. We collated data from the 4 pediatric and 3 NICU facilities in the state to provide a cumulative statewide antibiogram.
Results:
Methicillin-susceptible Staphylococcus aureus was more prevalent than methicillin-resistant Staphylococcus aureus. Pseudomonas aeruginosa, Citrobacter koserii, and Acinetobacter baumannii were isolated in only 1 NICU.
Conclusions:
These antibiograms should improve empiric prescribing in both the inpatient and outpatient setting, providing data in some areas that historically do not have pediatric antibiogram to inform prescribing. The antibiogram alone is not sufficient independently to improve prescribing but is one important aspect of stewardship in the pediatric population of South Carolina
Effects of a weight loss plus exercise program on physical function in overweight, older women: a randomized controlled trial
BACKGROUND:
Obesity and a sedentary lifestyle are associated with physical impairments and biologic changes in older adults. Weight loss combined with exercise may reduce inflammation and improve physical functioning in overweight, sedentary, older adults. This study tested whether a weight loss program combined with moderate exercise could improve physical function in obese, older adult women.
METHODS:
Participants (N = 34) were generally healthy, obese, older adult women (age range 55-79 years) with mild to moderate physical impairments (ie, functional limitations). Participants were randomly assigned to one of two groups for 24 weeks: (i) weight loss plus exercise (WL+E; n = 17; mean age = 63.7 years [4.5]) or (ii) educational control (n = 17; mean age = 63.7 [6.7]). In the WL+E group, participants attended a group-based weight management session plus three supervised exercise sessions within their community each week. During exercise sessions, participants engaged in brisk walking and lower-body resistance training of moderate intensity. Participants in the educational control group attended monthly health education lectures on topics relevant to older adults. Outcomes were: (i) body weight, (ii) walking speed (assessed by 400-meter walk test), (iii) the Short Physical Performance Battery (SPPB), and (iv) knee extension isokinetic strength.
RESULTS:
Participants randomized to the WL+E group lost significantly more weight than participants in the educational control group (5.95 [0.992] vs 0.23 [0.99] kg; P < 0.01). Additionally, the walking speed of participants in the WL+E group significantly increased compared with that of the control group (reduction in time on the 400-meter walk test = 44 seconds; P < 0.05). Scores on the SPPB improved in both the intervention and educational control groups from pre- to post-test (P < 0.05), with significant differences between groups (P = 0.02). Knee extension strength was maintained in both groups.
CONCLUSION:
Our findings suggest that a lifestyle-based weight loss program consisting of moderate caloric restriction plus moderate exercise can produce significant weight loss and improve physical function while maintaining muscle strength in obese, older adult women with mild to moderate physical impairments
Handwashing and Ebola virus disease outbreaks: A randomized comparison of soap, hand sanitizer, and 0.05% chlorine solutions on the inactivation and removal of model organisms Phi6 and E. coli from hands and persistence in rinse water.
To prevent Ebola transmission, frequent handwashing is recommended in Ebola Treatment Units and communities. However, little is known about which handwashing protocol is most efficacious. We evaluated six handwashing protocols (soap and water, alcohol-based hand sanitizer (ABHS), and 0.05% sodium dichloroisocyanurate, high-test hypochlorite, and stabilized and non-stabilized sodium hypochlorite solutions) for 1) efficacy of handwashing on the removal and inactivation of non-pathogenic model organisms and, 2) persistence of organisms in rinse water. Model organisms E. coli and bacteriophage Phi6 were used to evaluate handwashing with and without organic load added to simulate bodily fluids. Hands were inoculated with test organisms, washed, and rinsed using a glove juice method to retrieve remaining organisms. Impact was estimated by comparing the log reduction in organisms after handwashing to the log reduction without handwashing. Rinse water was collected to test for persistence of organisms. Handwashing resulted in a 1.94-3.01 log reduction in E. coli concentration without, and 2.18-3.34 with, soil load; and a 2.44-3.06 log reduction in Phi6 without, and 2.71-3.69 with, soil load. HTH performed most consistently well, with significantly greater log reductions than other handwashing protocols in three models. However, the magnitude of handwashing efficacy differences was small, suggesting protocols are similarly efficacious. Rinse water demonstrated a 0.28-4.77 log reduction in remaining E. coli without, and 0.21-4.49 with, soil load and a 1.26-2.02 log reduction in Phi6 without, and 1.30-2.20 with, soil load. Chlorine resulted in significantly less persistence of E. coli in both conditions and Phi6 without soil load in rinse water (p<0.001). Thus, chlorine-based methods may offer a benefit of reducing persistence in rinse water. We recommend responders use the most practical handwashing method to ensure hand hygiene in Ebola contexts, considering the potential benefit of chlorine-based methods in rinse water persistence
Autism Spectrum Disorder Among US Children (2002â2010): Socioeconomic, Racial, and Ethnic Disparities
Objectives. To describe the association between indicators of socioeconomic status (SES) and the prevalence of autism spectrum disorder (ASD) in the United States during the period 2002 to 2010, when overall ASD prevalence among children more than doubled, and to determine whether SES disparities account for ongoing racial and ethnic disparities in ASD prevalence
